ABSTRACT

“The future will either be green or not at all.”

Bob Brown

“I'm eternally optimistic about the future. I believe that if we are committed towards it and if we continue to educate people and get the whole world community to implement green features and aspects in not just the built environment not just in their lifestyles but in their businesses in their industries then we're heading towards a green future.”

Ken Yeang

Transit-Oriented Development is a term first used by Peter Calthrope, an American planner in 1993. This relatively newer design paradigm adopts a holistic approach towards sustainability by directing people to use public transit systems, thereby decrementing the private ridership and hence congestion. It proposes integration of land use on a regional scale. It became a theoretical foundation of the movement known as New Urbanism.

With rapid increase in urban population over few decades, Indian urban cities are choking. With the private vehicle ridership incrementing significantly, there is a constant threat to environment. It is time that an inclusive approach is adopted and buildings are designed keeping in mind their impact on the environment.

Biomimicry involves mimicking nature’s processes in built environment to achieve a sustainable design. Both Biomimicry and TOD, if amalgamated together can engender great results in bringing forth a sustainable design.

1. INTRODUCTION 1.1. OVERVIEW In recent years, India has witnessed rapid urbanization with the urban population rapidly growing in size and area. According Acc to a World Bank report, urbanization in India has increased from 17.29% in 1951 to almost double in 2017 resulting in Indian cities to grow at a faster pace with respect to other urban cities of the world. This horizontal growth of urban cities has been highly unsustainable over the years and has been the cause of various root problems like urban sprawl, increased trip lengths, higher usage of Concrete Jungle, New Delhi private motorized vehicles, all of which result Source: Google Earth in pollutions of different kinds. Private vehicles in addition to that have had some ever-lasting lasting effects on the urban cities and have played an important role in such kind of development. To address these issues, Is this a future we dreamt of? metropolitan cities in the past 2 decades have ha I believe not. worked upon strengthening the public transit facilities by developing Mass Rapid Transit Systems (MRTS) such as the Bus Rapid Transit System (BRTS) and Metro Rails.

What needs to change?

“We advocate the restructuring of public policy and development practices to support the following principles: neighborhoods should be diverse in use and population; communities should be designed for the pedestrian and transit as well as the car; cities and towns should be shaped by physically defining and universally accessible public spaces and community institutions; urban spaces should be framed by architecture and landscape design that celebrate local history, climate, ecology, and building practice.” (Carlton, 2007)

Addressing these issues, there has been a relatively newer design paradigm known as Transit Oriented Development or TOD. It is essentially any development, micro or macro, which is focused around a transit node, and facilitates complete ease of access to the transit facility, thereby inducing people to prefer to walk and use public transportation over personal modes of transport. (Calthrope, 1980) With mix of land-uses and optimized development around a transit corridor, TOD is the key for low-carbon and compact development. Under this scheme, the density of adjoining areas (areas under the Influence Zone) is increased and high-rises are placed along the transit corridors to accommodate a wide variety of uses.

It was acknowledged in the developed countries that the close integration of land use activity and transport infrastructure (generally seen as public transport) could be one means of creating the means to achieve more sustainable travel outcomes. The concept of Transit Oriented Development originated from these efforts. Transit oriented development (TOD) encourages public transit ridership by locating residences, jobs, and activities near transit stations. (WRI India, 2014) The Primary Goals of TOD are:  Reduce/discourage private vehicle dependency and induce public transport use – through design, policy measures and enforcements.  Provide easy public transport access to the maximum number of people within walking distance – through densification and enhanced connectivity.

REGION

CORRIDOR

STATION

SITE: It includes the design of streets, buildings and public spaces.

STATION: It includes the entire station area in the Influence Zone of TOD. CORRIDOR: A transit corridor is best defined as the walkable area(s) around all the stations along a transit line.

REGION: Planning at the regional scale serves to integrate regional goals, such as decreasing traffic congestion and improving public health, with regional contexts, such as consideration of population growth and the location of major employment centers.

All the above-mentioned stages will have the same primary goals but requirements vary accordingly. However, the general requirements being: o Housing o Commercial Ares/ Offices o Retail Areas

1.3. BIOMIMICRY Nature and all natural processes have had a long history of sustaining themselves. All the organisms, plants and animals have evolved and made themselves resilient to the everchanging environment, which has been the key factor of their survival over the centuries.

Biomimicry is an approach to innovation that seeks sustainable solutions to human challenges by emulating nature’s time-tested Figure 1.4: Golden Ratio in nature (FORM BASED BIOMIMICRY) patterns and strategies. In a built Source: (Ecosalon) environment, Biomimicry sought to replicate nature’s processes to achieve a sustainable design.

Biomimicry can be:  Form-based Biomimicry  Function-based Biomimicry “You could look at nature as

being like a catalogue of products, and all of those have benefited from a 3.8 billion-year research and development period.”

(Pawlyn, 2019)

Biomimicry focuses on the circularity of the natural environment and urges to replace the present linear practices with a circular approach. It works on the principle that there is no waste in the environment, meaning waste for one is a resource for others.

Biomimicry can help in achieving sustainability keeping the following parameters in mind:   

A radical increase in resource efficiency.

Linear to closed loop.

Fossil fuel economy to solar economy.

While existing technologies and techniques are crucial in the short and medium- term, Biomimicry holds the potential to form an important part of long-term solutions to climate change and therefore, contribute to a Regenerative Development.

The key distinction of architecture that is a true reflection of ecological understanding is not that a building is designed that looks as if it has emerged out of a living process, but instead is the creation of spaces that become living processes over various spatial scales.





Provision of open land and urban green space/rooftops/vegetation for storm water management and provision of cooling microclimates.

Provision of wildlife corridors (to allow for the changing ranges of species and thus the preservation of urban biodiversity and the ecosystem services it provides.

Restricting heights and density of buildings to allow for increased ventilation.

Implementation of policies or technologies to prepare for climate change impacts. For example, changing building codes to reflect increased extreme weather events and different heating and cooling needs in the future, or increasing urban vegetation or high albedo roofs. (Zari, 2018)

Figure 1.7: Trajectory of Ecological Design Source: (Regenesis)

Regenerative architecture embraces the environment and uses the millions of years of engineering and evolution as the foundation for a structure. Regenerative design is based on the premise that everything we build has potential for integration of the natural world as an “equal partner” in architecture.

2.1. CONTEXT OF TOD IN DELHI Delhi has developed rapidly into an urban agglomeration encompassing smaller urban centers in its vicinity as well. The population of Delhi witnessed steep rise from 1.74 million in 1951 to 6.75 million in 2011. (Census of India, 2011) The average annual exponential growth rate of population during 2001-11 2001 has been recorded as 1.92% and overall population density has hiked from 9,340 persons per sq.km. in 2001 to 11,320 persons per sq.km.,, being the highest as compared to other parts of the country. Of this, the urban density is even higher, at 14,694 persons per sq.km. (Census of India, 2011).

2011) In terms of spatial development, the city has grown more horizontally lly than vertically due to building bye-laws laws and norms. Due to this urban sprawl, the travel distances, number of daily trips, traffic congestion, pollution, energy use, etc. are increased drastically.

Inspite of New Delhi’s recent investments in public transit systems, the current lack of connectivity, lack of safety for pedestrian, cyclists and women has further compiled on to other problems like traffic congestion, etc. The problem has now reached a state where wh it is feared that it might have an irreversible damage on the city’s fabric. (HUDCO, 2016) Some areas of Delhi have even reported AQI surpassing 1000 in November, 2019.

Vehicular emissions contribute to 70% of the air pollution tion in Delhi. Schemes such as OddOdd Even by Delhi Government also did not do much good to the air quality. Major arterials of the city are presently down to 10 km/hr average speed during peak hours. 70-30 70 (Public-Private) Private) modal share in favour of public transportation nsportation by 2021 is one of the main objectives of Delhi Government. (Bhatia, 2019)

Transit Oriented Development was chosen as an effective solution and government launched a project in Kadkardooma which is currently at the tender and design stage.

Proposal for a ‘Lake View Complex’ at Trilokpuri is also under consideration. Apart from this, government has also identified four metro corridors for further development of TOD in New Delhi.

“We have worked on a philosophy of creating memorable destinations within the green, building on the role of Sanjay Lake as a place dedicated to engaging the public in the development of a new cultural identity on one of the waterfronts in the city through artistic expression.”

(DDA_Official, 2019)

2.2. VALIDITY OF PROJECT The integration of Transit-Oriented Development Policy into the Master Plan of Delhi-2021 gave way to the proposal of the ‘Lake View Complex’ in Trilokpuri. DDA has desired to develop the 10.26 hectares of land based on TOD and the project is intended to showcase Sanjay Lake Park through mixeduse development of the lake view complex housing residential, hospitality, and publicoriented uses. The development shall comprise service apartments, corporate and commercial components, public plazas and other recreational facilities. ‘Lake View Complex’, as envisioned by DDA would enhance the footfall of visitors of the lake and make the place active round the clock. This would also ensure the overall development of Trilokpuri area.

3.1. GUIDELINES FOR TOD COMPONENTS (SITE LEVEL) Master Plan Delhi, 2021 has been amended to include the provisions of the TOD policy. At the core of the policy is the aim to promote high density development within 500 meter radius that translates into a walking environment around a metro station. Termed “influence zones”, these areas will see a growth in population with the increase in floor-area ratios (FAR), mixed use development that will produce housing units as well as increase concentration of jobs and encourage people to either walk or use public transit. The focus would be on creating interactive edges between buildings and streets with activity thereby ensuring safety, which is a high priority for the city of Delhi. By creating walkable environments, the policy aims to create an equitable space for movement of all. With one of the highest percent of land dedicated to road network amongst cities in the world, Delhi’s TOD policy will need to provide convenient world class infrastructure in order to shift people from their personal vehicles. (WRI India, 2014) 3.1.1. SETBACKS/EDGES The urban edge can be defined in terms of the visual boundary of a space. It is essentially a transition zone that facilitates exchange of information between territories. Within the TOD policy, the idea is to have permeable edges, thereby reducing the emphasis on the concept of setbacks.

For projects above 10,000 sqm, 12 m is to be left on 3 sides and no setback is required to be left on the front side facing main road.

(DDA, 2015)

Figure 3.4: Minimum RoW of main road Source: (WRI India, 2014)

Points to consider:  In case the permissible coverage is not achieved with the above given setbacks, the setbacks of the preceding category may be allowed.  TOD schemes shall be located on existing roads having a minimum width of 18m RoW. In TOD schemes, any edge of plot facing an existing public RoW >18 m shall be considered as “front”.  The setbacks are subject to requirements of height and ventilation as per building byelaws. TOD schemes shall be planned as per above setback norms, while endeavouring to ensure that all dwelling units get a minimum 2-hour solar access in at least one habitable room on the shortest winter day, and have the option for natural ventilation.  ESS (Electric Sub Station) wherever required to be provided within the plot setbacks.

3.1.2. ACTIVE FRONTAGE The main building facade(s) shall face the public street(s) without setback and have an active frontage to facilitate visual surveillance of streets. ≥50% building frontage at built-to RoW line to have active frontage. There is no minimum active Figure 3.5: Active Frontages frontage requirement when RoW is ≤12 m.

Source: (WRI India, 2014) Active frontages include arcades, shopfronts, entrance doorways, access points, entry / exits and transparent windows of active areas facing the main street.

Commercial frontages shall have minimum 50% transparency (untinted) at Ground Figure 3.6: Stilt parking to be on rear side Floor level.

Figure 3.8: Density and FAR relation Source: (WRI India, 2014)

3.1.3. FAR AND DENSITY The floor area ratio (FAR) is representative of the total floor area of the building as a fraction of the total area of the plot the building is located on. It is used by government bodies in zoning regulations as an instrument to control the density of a place by imposing permissible FAR norms.

Points to consider:  TOD norms of FAR and density may be availed through the preparation and approval of comprehensive integrated scheme of minimum size 1 Ha, with maximum ground coverage of 40%. In case of MRTS/ Government Agencies, the minimum plot size for development shall be 3000 sqm.  For any integrated scheme, a max. FAR of 400 and a maximum density of 2000 persons per hectare (PPH) i.e. approx.

450 du/ha is permissible. The entire amalgamated plot will be considered for calculating the FAR and density.

FAR utilization shall not be less than 200. Mandatory EWS FAR of 15% over and above the maximum permissible FAR shall be applicable.  All residents residing in that scheme area shall have to be accommodated within the same scheme only, with no induced displacement of existing residential population.

3.1.4. MIX OF LAND USES In all integrated schemes, a minimum of 30% of overall FAR shall be mandatory for Residential use, a minimum 5% of FAR for commercial use and minimum 10% of FAR for community facilities. At least 50% of the total FAR shall be as per ZDP use.

“TOD is not just about mix of land-uses, it rather is about the integration of built-form with transit facilities in vicinity.”

Points to consider:  The minimum component of 30% residential shall comprise of units not more than 93 sqm. (1000 sqft).  Within the 55% flexible use, in case Residential use is provided, DE would have the option to provide homes of any/larger size, as per the demand.  EWS FAR of 15% over and above the permissible FAR will be applicable.  Minimum requirements for 30% Residential and 5% Commercial will not be binding on transportation, Government and PSP land uses.  In case of residential land use, activities prohibited are as follows: o Retail shops of building materials [timber, timber products, marble, iron and steel, (gravel, cement and sand], firewood, coal and any fire hazardous and other bulky materials. o Repair shops / workshops of automobiles, tyre resoling and retreading, and battery charging. o Storage, go-down and warehousing. o Junk shop o Liquor shop o Printing, dyeing and varnishing.

4.1. INTRODUCTION Named after Karkardooma locality in East Delhi, Karkardooma Metro Station is an interchange station located between Blue and Pink Line of Delhi Metro. The proposed development will be the pilot project for TOD in India which consists of a variety of highhigh density, mixed-use, mixed-income building with short distance of rapid public transport network. With goals to minimize the need to commute for work or recreation, and making urban development more sustainable the work on the capital’s first Transit Oriented Development (TOD) has begun. The integrated development of the hub will bring together metro station, residences and workplaces; and recreational spaces such as museums.

Designed by Dikshu C. Kukreja, managing principal of CP Kukreja Architects, the site location has 2 metro stations and is in proximity to a railway station and an interstate bus terminal. al. According to TOD Policy for Delhi, developments along a transit corridor can have higher Floor Area Ratio (FAR) to accommodate more residential, office and recreational spaces in walking or cycling distance of transit station.

4.2 LOCATION AND APPROACH Location coordinates: ordinates: 28°38’55”N 77°18’17”E Located in close proximity to Anand Vihar Terminal, the site is 60 acres in area.

Surrounded by Maharishi Valmiki Marg on West, Bhartendu Harish Chandra Marg and Maharaja Surajmal Marg on North, the site is bounded by roads on all sides. The nearest landmarks include District Court, Karkardooma and Karkardooma Metro

COMMERCIAL AREA The site contains total area of 1,69,551sq.m as commercial area which is approximately 20% of the total FAR. Out of this, an area of 80,000 sqm is for the retail areas. The commercial areas are generally placed on the upper floor levels so s that the lower levels could be the residential population. To abide by the norms and principles of TOD the commercial areas are placed on the edge to avoid setbacks. The concept of “Eyes on Street” can be followed without compromising the privacy of residential dential blocks. Almost every block has commercial areas, behind which are the residential areas having a common central green area.

Bounded by the Ring road and the Africa Avenue the commercial part of the site has the highest degree of visibility. Thus important office buildings like EIL, Cama ama Bhawan are constructed alongside. This not only has given rise to “landmarks” thereby increasing the image ability of the centre but also focuses public attention to the commercial zone.

The luxury hotel, Hyatt Regency also occupies a prime land and forms a landmark.

Urban design vision of this design is to achieve harmony in the aesthetics of built environment and public spaces to be climatically suitable to become public places, segregation of pedestrian and vehicles. vehicles Cars are undoubtedly considered a necessity and treated like one but importance rtance is given to pedestrians. Height eight of buildings is regulated by fixing the FAR in relation to the plot size.

August Kranti Bhawan mediates mediate the scale and activity between the rest of the complex and Mohammadpur Village.

Edge Conditions Edge conditions are the boundary zones where most of what intrigues us happens. happens In case of Bhikaji Cama Place, the site shows variable edge conditions at different locations.

These edge conditions have changed with time; therefore, what is seen now may or may not be same as it was planned.

In many stretches, it has also been observed that edge conditions vary within a few meters.

Hierarchy of Roads: Ring Road (64m), Vivekanand Marg (45m), Africa Road (35m), Distributory Road (15m).

The Bhikaji Gama Place metro station is a newer addition to the site and Gate No. 3 hinders movement and vision. This way, the station has become a visual barrier.

The station has also resulted in creation of various level differences which are not universally Figure 5.8 accessible.

With GAIL building on the left and Hyatt Regency on the right, the secondary road has surface parking along GAIL Building. The edge along Hyatt Regency is dead on account of the boundary wall; leaving a little width for pathway to walk upon.

Due to the same, many persons prefer to walk on the road instead of the pathway.

With NBCC building rising 5 levels on the left and Hyatt Executive Suites’ building on the right, the surface parking on the secondary road is shifted to the other side; along Hyatt Building. The edges on both sides are quite harsh on account of the boundary walls.

Widths of pedestrian walkway on the NBCC building side is more as compared to that on the other side.

With a structure rising 9 levels on the left and triple storey HUDCO building on the right, there is a wide green belt on the latter’s side.

However, 2-wheelers are being parked in the green belt due to lack of along-the-road parking spaces.

The road on one side is taken up for car parking. There is a vacant plot for parking but people do not prefer to park inside. They rather prefer Figure 5.14 parking on the road itself.

Figure 5.15: Entry/Exit points of the site.

Figure 5.16: Seating spaces are taken up by Informal Sector.

The whole layout of the site is in 2 levels: Ground Level and Upper Ground Level. The lower level is taken up by service courts that are primarily used for parking and on the upper level is the main pedestrian plaza that hosts all the informal and recreational activities. The level difference between both plazas is 3.15 m. Upon entering the main plaza from Metro Station’s side, a person is welcomed with a seating under the canopy of a huge tree. A visual axis guided by 2 planes of adjacent buildings is formed that welcomes and guides a person into the site. There are a series of pedestrian plazas. Surrounded by buildings on both the side, Plaza 1 is the main pedestrian plaza of the site. This houses maximum informal sector and is lively; even in after-hours. hours. During lunch time, there is a lot of footfall in this plaza on account of various eating joints present. This is the primary reason of footfall touching third th highest during 1 pm.

Plaza 1 is connected to Plaza 2 via PNB building. The First Floor of this building (Upper Ground Floor of site) acts as an axis to move to and fro both the plazas. There is no direct access to onee plaza from the other after working hours as PNB building is locked Figure 5.17: Daily footfall according to time during night. Where Plaza 1 is lively most of the time, Plaza 2 is non-active active. Due to its large proportions, sense of enclosure is lost in this plaza, thereby making it less secure.

Service Courts 3 and 4 are being used for parking purposes and have some landscaped area. These courts are connected with each other from Ground Floor (Lower Lower Ground Floor of the site). Below Plaza 1 and 2 are also parking lots. The site was developed in an era Figure 5.18: Parking in service courts and of cars starting to dominate the lifestyle; columns are supporting pedestrian plaza on therefore, adequate parking can be seen.

Landscaping In the complex, buildings are placed along open courtyards, which are not maintained well. Shady trees are planted along the parking. Small water bodies with sculptures in centers are there in a few service courts. courts Due to lack of seating in the courts, parapet along the court is used for sitting.

Figure 5.20: Peepal tree is provided in the open courtyards. This tree is generally found in isolation.

There is an unplanned landscape scheme of the site. As the entire structure is dominated with office buildings, no recreational eational spaces, outdoor seating spaces have been provided.

Row of shady trees line the internal roads of CBD. There is a lack of seating places in the central courtyard. Cemented seating is provided around the trees which serve as the only outdoor seating space. The central courtyards provided are not given any attention except the ones in “The Ansal chambers 2” and HUDCO Bhawan. The open spaces due to being mishandled are become garbage dumps for eating joints. joints The Complex has no feature to attract the public blic after office hours.

The landscaping of Hyatt Regency is properly planned and well executed. There are water wat bodies along the drive way and various types of trees are planted which add to the grandeur of the hotel building. Concept of Green Wall is also adopted in the residential block of the hotel. It is also observed that good landscape scheme is followed lowed around prestigious office buildings. The private owners have got their own landscape scheme implemented.

However, public areas have a negative aspect.

Spatial Analysis The height of building blocks varies. The variety in mass volumes gives the visitor a rich, interesting experience as the spaces open out into each other; according to the usage of the respective block. Architectural controls regulate facades of all the buildings. There is dynamism and clarity in the layout. The sunken courts used for parking further add to the dynamism of the place.

The buildings on the Southern side of the site (August Kranti Bhawan) are low-rise low in order to relate to the surroundings; as there is lowlow rise Mohammadpur village on the rear.

A newer addition to the site has been made.

Hyatt Regency is in ownership of a separate building with IndusInd bank on ground floor and luxury apartments on upper levels. This is now the highest building of the site.

Figure 5.25: Connection of buildings on upper floors

During off-hours, SCO’s act as dangerous pockets due to which other areas (especially ( Punjab National Bank)) are crime ridden as they have no link to the main road where security is provided.

The buildings are connected to each other either on ground or on upper floors. Either 3 floors are connected on thee ground or the 3 top-most most floors are connected. This gives a sense of scale to the visitor. Small government buildings are also connected in similar manner. This unification can be noticed elsewhere too.

Public Toilets There are two public toilets on the site. One is maintained and run by O.P Jindal group and the other is by some non-private body. The former one is in good condition and seems to be a newer addition to the site while the latter is locked and is not functional and seems to be constructed during construction of site.

Toilets run by O.P Jindal group have both female and male toilets; with separate area for urinals. These toilets also function during evening. There is also provision for disabled persons, which is not the case for non-private body operated toilets on the other side.

Figure 5.31: Image of toilets operated by O.P Jindal Group

The non-private body operated toilets have been locked and the approach pathways are being used for two-wheeler parking. The services such as water tank are present there but are non-functional. The main reason for the locked public toilets is the inadequacy of maintenance. As these are located in proximity to the main road, these should have been functional as they cater to many shops nearby. Offices have their own washrooms indoors but accessing a public washroom is a difficult task for shopkeepers and visitors.

However, there are washrooms in Petrol Pump which can be accessed by public.

The planning of the building has been done keeping in mind the orientation in order to provide comfortable interiors as well as exteriors. As seen in the adjacent section, an interesting type ype of massing can be seen on the inner façade facing courtyard. This has been done in order to have shaded corridors during afternoon as projections can be seen .on the side facing south. As the same typology is used for corridors facing other directions too; oo; therefore being a passive design on one hand, this also creates a dramatic effect in terms of scale of the building.

Figure 5.43: First Floor Plan Source: (HUDCO)

First Floor The First Floor of the building houses offices of HUDCO and railways. Being a linear plan, the corridors on the either side of the plan are connected; which in turn visually defines an area. Most of the areas are naturally lit during the day. However, the corridor on the Eastern side does not receive any natural light. FFL to FFL height of this floor is also 3.3 m. There is a pantry on this floor but no provision for service lift has been provided.

The adjacent conceptual section is visible in case of staircase. Here, in order to have passive cooling, vent has been left at the top so as to make way for warm air to escape; thereby resulting in the natural circulation of Figure 5.44: Conceptual Section of Staircase air.

LEGEND

Designed by master architect, Raj Rewal, the EIL building is the tallest structure of whole Bhikaji Cama Place complex. Engineer India Limited building houses administrative, design, financial and public relation offices of a public sector organization dealing dea in design consultancy for industry and technology in India. The design concept is based on four cores on the corners containing lifts, staircase and services, resulting in a large hall in the middle for flexible office planning. These cores act as major structure element and along with four central shear walls support and average office floor of 54m X 24.6m. The form of the building is derived with the aim of saving energy. The service cores are designed in such a manner that they also cut down harsh hars glare from the south-west, west, The stepping of floors within the cores and extending different floors to the east and west ends of the building, creates a zone of surface under shadow, thus reducing temperatures. The structural cores along with the extended floors form a giant sun breaker.

The Lower Ground Floor is used for parking purposes and a series of steps take visitors to the Upper Ground Floor that houses reception and double height atrium. The atrium is spacious and is used as waiting area for the visitors. High security can be seen in the building and only persons with permission can access ss upper floors. Massing of the building is done in such a way that the building takes in maximum of North Sun but Sun is blocked on the South with the creation of steps. This ensures comfortable indoor environment without the need of air conditioning.

The site has direct link to Bhikaji Cama Place Metro Station and sits on the Ring Road.

Pedestrian link is strengthened with the metro station to improve pedestrian access to the site.

Except for metro station, other linkages are not prominently noticeable.

Beyond the main road, there are multiple layers of pathway and/or service roads surrounding the site on all 4 sides, which are of variable widths.

The pathways cater for pedestrian movement with tactile tiles only on pathways adjacent to metro station for universal accessibility. These pathways also serve as spaces for informal food kiosks and cigarette shops. Edge conditions largely vary around the site at different locations according to functional requirements.

Multiple layers included in the edges serve different functions.

The site is trapezoidal in plan and rigidity of the site compliments the rigidity of building layout.

The site plan is in 2 levels according to the function it serves. Lower level is used as parking and upper level is used as a pedestrian plaza that hosts almost all the informal activities.

The planning of the site plan is in 2 levels namely Lower Ground and Upper Ground, the former one being supported with columns and beams.

Multiple entry/exit points are there for the site.

Some of these are marked with building connections on upper floors. Stepped pedestrian access points are there, taking a person directly on to the Upper Ground Floor pedestrian plaza.

Widths of entrances are in accordance with their functional requirements. Pedestrian entrances are narrow. However, service and vehicular entrances are wide.

Voids between buildings act as entrances for site.

Vehicular circulation is along the site periphery and on Lower Ground level of the site (that acts as service courts for parking purposes). Parking bays are demarcated with curbstones.

The pedestrian movement is on the inner and peripheral side. Inner courtyards are rectangular in plan. All the buildings are connected with pedestrian plazas on Upper Ground Level.

Pedestrian movement on inner side is along various courtyards that cater for informal sector.

Pedestrian circulation is hosted by plazas on Upper Ground Level. This level is free from Vehicular Movement.

There are multiple plazas on the site. Some are enclosed on all sides by various buildings.

However, some are open on few sides. The former ones are safer than the latter.

The plazas function as spaces for informal sector to sell commodities and for recreational facilities.

The plazas being orthogonal are on Upper Ground level and are supported by beams and columns.

Outdoor seating is fixed and in-built.

Aesthetically pleasing landscape variety is used wherever required.

Landscape is in accordance with climatic conditions of the region and is done considering the orientation.

The seating is fixed and made out of sandstone.

Integration of informal sector makes the place lively. The main area for this sector is the central courtyard. Arrangement is along pre-existing seating.

Informal sector is adjacent to hotspots of the site.

Either temp. structures are made or hawkers simply sit and sell commodities.

Irregular skyline is observed due to varying heights of various buildings.

Newly constructed Hyatt building dominates the skyline with premium apartments. All other buildings are relatively shorter in height.

PARKING Except for the minister’s block (Block A) parking in close proximity to Gate 3, there is no major surface parking on the site. Rest of the parking for office staff and visitors is either on stilts or in the basements.

There is a total provision for 2500 vehicles to be parked inside the complex. The total covered area being 116,000 sqm, E.C.S comes out to be 2 cars per 100 sqm area.

Due to maximum persons coming with drivers, the latter usually sits in the car for most of the time and therefore the cars can be parked in a haphazard manner; without causing delay to any person.

There is also a space for few cars to be parked in close proximity to all the blocks but it is only for higher officials of that particular block.

STILTS AND BASEMENTS Basements of all the blocks are combined and this makes the basement to be in a circular plan. One main two-way way circular ramp feeds basements and cars go down a 7.5m wide ramp (each aisle being 3.5 m wide) with approx. 1:12 slope. In addition, there are 5 secondary ramps (7.5m wide each) and these are dedicated to particular blocks. All the aisles are 7m wide. Wherever there are Fire Escape Staircases, care has been taken to keep the parking area in front of it vacant in order to have smooth evacuation.

A central skylight ensures diffused light in the basement throughout the day, hence ensuring safety in the basements as well. However, the ventilation of basement is through ducting system placed 8’ high on every basement.  FFL to Ceiling Height: 4m.  FFL to Beam bottom Height: 3.8m  Water channels run below the roof and water sprinklers are at 2 m distance.  Basements house service areas too. There are 5 Water Chillers, 5 big Water Pumps and 8 Transformers.  All the vents of the basements open on to the site.  Height of service area: 8m  Basement 1 houses Waste Disposal Room.  Basement 3 houses staff changing lockers. `

A-Block is a 6-storey storey structure that houses offices of ministers and is located on the Northern side of the site.

It is a North West – South East oriented building and is stepped on the Western façade.

The form of the building is an amalgamation amalgama of a rigid and an irregular form.

The plan is in shape of an arc with a central skylight that brings in natural sunlight, thereby ensuring interior spaces to be naturally lit throughout the day.

The rear entrance of the building (from the side of Skylight) is 5m wide and recessed.

The building has a recessed entrance.

There is a feeling of huge entrance on the outside. However, foyer of the building does not offer grandeur feel on account of the low height of metal down ceiling.

On the rear side of Ground Floor, there is a banquet hall kind-of of space where lunch on special occasions is served to the ministers.

However,, there is no dedicated area for the preparation of food. It is done outdoors.

Large amount of seating is given outside the building as there are a lot of people around the building most of the time.

To cater to a large amount of persons visiting the building ilding on daily basis, the corridors are wide and house benches for seating.

On the Ground Floor is the only food canteen of the complex and it gets really busy during lunch hours.

Conference Rooms are circular in shape and are housed on every floor.

Terraces formed on the upper floors on the Western façade are rarely used.

HVAC System The building is fitted with a central air conditioning system using water cooled centrifugal chillers to provide summer / monsoon cooling and winter heating. The salient feature of the HVAC system design include optimization of power demand by installation of Energy Recovery Wheel (ERW) in the fresh air system, to reduce the refrigeration load by 80% which in turn will also reduce the air conditioning plant load by 12 -15%.

The design also envisaged mechanical ventilation for the car parking area, toilets, pantry, plant room and other similar areas.

Mechanical ventilation for basement involves 10 air changes per hour in case of fire; same would be increased to 30 air changes per hour.

Water Supply and Sewage System City water supply from Delhi Jal Board is the major source of water to the complex. Two separate connections are provided, one for MCD and other for the remaining complex.

Tube wells are developed as an alternate water sources and for other uses like air conditioning etc. Water from tube well feed the raw water tank and depending upon the analysis report, minimum of pressure filter, softener and chlorination are proposed for treatment of water.

Two systems for water distribution, which include gravity system and hydro pneumatic system, are considered for the project. Gravity system with terrace water tank is utilized for 28-storiedtower block, whereas for the 6storey block, hydro pneumatic systems are employed.

The site has linear linkage from the New Delhi Railway Station and also from Connaught Place.

The road connecting site to railway station is vehicular; with little attention towards pedestrian movement.

The linkage of site to surroundings is vehicular.

Beyond the main road, there is a single layer of pathway surrounding the site on 3 sides, which is of variable widths.

The pathways cater for pedestrian movement with tactile tiles for universal accessibility. These pathways also serve as seating areas for rickshaw pullers and auto drivers.

Layers cannot be seen in edges. These were abrupt.

The site is rectangular in plan and rigidity of the site is in contrast to building plans, which are curvilinear.

The site plan is in 2 levels according to the function it serves. Lower level is used as stilt parking and upper level is for building functions and outdoor spaces.

The planning of the building footprints on the site is in accordance with structural grid of each block.

The entrance gates are flushed with boundary wall.

Gates are 13.3m wide in order to let in emergency vehicles during any mishap. There are separate smaller gates for pedestrian entry/exit.

The entrances directly face surrounding distributory roads.

Vehicular circulation is along the building periphery on the outside. Curvilinear roads connect each block to entrance gates.

Having vehicular roads on the building periphery, the Northern side of the site is only for pedestrian movement. All roads act as Fire Tender Movement.

Vehicular roads are on all sides except on North.

8.1. LOCATION Location Coordinates: 28°36’51”N 77°18’33”E Located in the capital city of India, the site is a 10.26 hectare of land surrounded by an artificial lake (Sanjay Lake) on one side.

Owned by Delhi Development Authority (DDA), the vacant site is proposed to be constructed on the principles of TransitTransit Oriented ented Development. The pink line of Delhi Metro runs North-South South to bifurcate the site in two distinct parts with Trilokpuri Metro Station on the southern part of the site. Sanjay Lake makes this development a destination and the surrounding high and medium mediu density housing pockets make it a high density gateway of the neighborhood.

Sanjay Lake is an artificial lake developed by Delhi Development Authority (DDA).

(DDA) The lake is spread over an area of approximately 17 hectares (42 acres) in the middle of a 69 hectares (170 acres) forest area, also known as Sanjay Lake Park. Sanjay Lake was developed in the 1970s by DDA and opened in 1982. The lake attracts some migratory birds and has many indigenous trees. A well-laidout fitness track is very popular with walkingwalking enthusiasts. The lake bound by Sanjay Lake Park, is surrounded by the residential colonies of Kalyanpuri and Trilokpuri on the eastern side and Mayur ayur Vihar on the Western side.

Sanjay Jheel is a huge rainwater fed lake. At times, the water supply was augmented by the back flowing Yamuna. During floods, it also received water through Hindon River channel.

Different types of birds can be seen see here till February end every year. According to Local birders, the lake hosts 90 varieties of birds.

Shovellers, Pintails, common pochard, tufted pochard, common teal, spot-bill, spot yellow headed wagtail and pied wagtail are some of the birds that commonly visit the lake. The migratory birds mostly come to the eastern part of the lake, as the water is deeper and the area is free from human disturbances. (Sanjay Lake, 2019) There is also an adventure park for recreation purposes. The park has been set up by Delhi Tourism and Transportation Development Corporation (DTTDC) in association with Delhi Development Authority (DDA) under PPP mode. The Adventure Park is claimed to havee been developed on a Wild West theme making extensive use of natural materials such as wood and jute rope and consisting of hut like structures.

“The connection of pink line of Delhi Metro is in its last leg of development. Mayur Vihar Metro Station would soon be connected to Trilokpuri Metro Station.

This would bring about a positive change in the area.”

The site falls in E-19 19 block of the Zonal Development Plan (ZDP) and it is evident in the Zonal Development Plan that major land use in Zone-E E is Residential and same is the case around the site. This strengthens the hope that once developed, the site would serve as a mixed land use hotspot of the area.

The commercial areas of the site would be benefitted as there is no predominant commercial area in close proximity to the site.

Transport Infrastructure Bus and metro rail are the two mass public transport networks operating in the area. area Autos are re being used for last mile connectivity.

An open gutter C: Petrol Pump channel runs along the Chand Cinema Road D: Petrol Pump across the site.

Chand Cinema Road Kalyan Puri Road Central part of the site is used by children for DMRC Pink Line recreational purposes. Many cricket matches are being played there. Free shelter also known as ‘Raen Basera’ provided by Govt. of Delhi also sits on the Southern end of the site.

Being surrounded by low and medium class neighborhoods, the issues of theft and drug prevail in the vicinity. Therefore, design has to be such that it prevents these issues through View of site from metro station design interventions. The coming up of the Clicked on 21.12.19 Police Post on the site would also al result in a regular check on the area.

According to the norms of TOD, minimum setback on the front side is 0 m. However, 12 m setback has been left for the construction of Police Station facing main road.

10. DESIGN CRITERIA FORM BASED 

In order to capture value, commercial areas will be located close to metro station whereas, housing for economically weaker sections is to be located far from the metro station and no provision for car parking will be given close to the same in order to prevent gentrification of poor.

Figure 9.1: Shortest Pedestrian Routes Source: Author’s Work

Figure 9.2: Voids as entrances Source: Author’s Work



ENTRANCE The voids formed as a result of connecting multiple parts of the same/different building(s) on upper levels could function as entrance to the site/areas of the site.



PEDESTRIAN PLAZAS Pedestrian plazas will be developed as a result of introvert site planning. These plazas shall be on a scale which human can respond to.



EDGE CONDITIONS Edge conditions of site and buildings should not be too abrupt and these should integrate various activities. Concept of thick façades is to be adopted on lower levels to integrate informal sector. Parking on ground floor of buildings should be enclosed by retail areas on the periphery in order to increase active frontage.

Figure 9.3: Introvert Site Planning Source: Author’s Work



Figure 9.4: Thick façades Source: Author’s Work

SITE PLAN

BUILDING FORM Clustered building forms shall be used in order to minimize the heat gain. This would also enhance the light and shadow effect.

95

Regenerative Transit-Oriented Development

FUNCTION BASED 

LAST MILE CONNECTIVITY Modal shift is to be achieved wherein people ditch their private motorized vehicles and adopt greener practices of walking, cycling and using non-motorized means of transit for last-mile commute.

This is ensured through design interventions by having relatively smaller and direct access routes for pedestrian.

Moreover, pedestrian pathways will be oriented in a way that they remain shaded during afternoon hours.

Skywalks shall be incorporated in design to enhance walkability at different levels.

Direct access to buildings to metro station can be made at concourse level. This would enable commuters to walk directly to their workspaces.



PEDESTRIAN AND VEHICULAR SEGREGATION There can be grade separation in plazas in order to segregate pedestrian and vehicular movement. Bollards are to be used for the same.



CONTEXT SPECIFIC PLANNING Keeping in consideration the social character of the area, small retail shops and informal markets or bazaars can prove to be value capturing services incorporated in design proposal.



REDUCED CONSUMPTION India receives abundant solar energy throughout the year. Therefore, to cash in the same, Solar panels can be incorporated on rooftops or on vertical façades to reduce dependence on the grid.



PLACE-MAKING In pedestrian plazas, urban design iconic elements/forms will be integrated which would enhance its user-experience. xperience.



LAKEFRONT DEVELOPMENT Revival of Sanjay Lake, presently in a dilaplated state is ensured with the development of lakefront in a way that it acts as a public space. Oriented on the windward side, air cleaning and fragrant plant species planted along lakefront would bring clean, fragrant air into the complex.

Informal semi semi-covered workspaces will be integrated which would help bring ring employees out in a natural setting, hence increasing efficiency.
